APPLICATION INSTRUCTIONS

SYSTEM OVERVIEWHYBRI-FLEX MC is a 100% solids, decorative chip system composed of a 1/8” POLY-CRETE SL body coat with a decorative chip broadcast. It uses a 16 mil CRYL-A-GLAZE G-201 broadcast coat, and two 16 mil CRYL-A-TOP T-301/T303 topcoats yielding a total nominal system thickness of 3/16”.

SURFACE PREPARATIONSurface should be profiled, clean, dry, oil free and sound. Shot Blasting is the preferred preparation method. Please refer to the master Surface Preparation Guide on our website for more information. Never feather edge HYBRI-FLEX MC, always terminate in a keyway groove at doorways, drains and exposed edges.

MOISTURE CONCERNSPlease refer to the Floor Evaluation Guidelines in the Contractor’s Center of our website for a step-by-step process to determine the condition of the concrete.

MIXING AREASelect a convenient mix area and protect the surface from spillage by covering with a sheet of plastic and a layer of cardboard. Be generous with the amount of space allocated for this function. The more comfortably your mixer works, the less likely you are to have a “mix error”. Please refer to the Mix Station video on our website for more information.

STORAGE CONDITIONSPOLY-CRETE SL must be stored dry. Exposure of the aggregate to moisture for an extended period will cause lumps. Do not allow resins to freeze. The shelf life is 6 months from the ship date in the original unopened container. Products must be stored in temperatures no less than 60°F and no greater than 85°F.

JOINT GUIDELINESRefer to the Joint Guidelines for complete details on our website.

APPLICATION METHODProper planning is essential for satisfactory appearance of the finished floor. Lay out installation in sections to allow full width to be finished in 20 minutes (@70°F) or less to assure absence of placement lines.NOTE: For each application of material and before mixing, mark your batches to ensure you achieve your spread rate targets. This is best accomplished by dividing your target spread rate by the width of the area being coated (or your planned wet edge). Example: If your spread rate is 100 square feet and your area is 20 feet wide you would make a mark every 5 feet (100 divided by 20 = 5).

PRIMERIn most applications HYBRI-FLEX MC does not require a primer. However, very porous substrates should be primed first with POLY-CRETE TF PLUS.A. POLY-CRETE TF PLUS is supplied in pre-measured units

consisting of one pail of resin, one container of hardener and one bag of aggregate (powder). Pour the POLY-CRETE TF PLUS resin into a 2-gallon pail; scrape bottom and sides with a mix stick to assure that all material is transferred to the mix bucket. Use the Poly-Crete pail to scrape the mix stick, never scrape mix stick on the side of the mix pail. Measure out 0.25 fluid ounces of POLY-CRETE HF ACCELERATOR, add to the mix bucket and mix the resin and accelerator for one minute. Pour the entire POLY-CRETE TF PLUS hardener into the center of the mix bucket. Using a ½” 850 RPM drill with a 4” dispersion blade, mix the resin and hardener for 30 seconds. Slowly add the POLY-CRETE TF PLUS aggregate to the resin and hardener and mix at 850 RPM for 1 minute. PRODUCT MUST BE MIXED WITH A 4” DISPERSION BLADE AND A ½” VARIABLE SPEED 850 RPM DRILL. DO NOT ADD HARDENER TO RESIN UNTIL BATCH IS READY FOR MIXING. FAILURE TO ADD ALL POLY-CRETE TF PLUS POWDER WILL RESULT IN IMPROPER CURE OF MATERIAL.

B. Pour the entire batch onto the floor in a 4 to 6” ribbon. Use a 1/8" V-Notch squeegee to spread the material at 90 square feet per kit and back/cross roll using a 18" wide,

BASECOATA. POLY-CRETE SL is supplied in pre-measured units

consisting of one pail of resin, one container of hardener and one bag of aggregate (powder). Pour the POLY-CRETE SL resin into a metal 5-gallon pail; scrape bottom and sides with a mix stick to assure that all material is transferred to the mix bucket. Use the Poly-Crete pail to scrape the mix stick, never scrape mix stick on the side of the mix pail. Pour all of the POLY-CRETE SL hardener into the center of the mix bucket. (If using POLY-CRETE NATURAL SL with pigment add the pigment to the resin and hardener.) Next, using a ½” 850 RPM drill with a 4” dispersion blade, mix the resin and hardener for 30 seconds. Slowly add the POLY-CRETE SL aggregate to the resin and hardener and mix at 850 RPM for 1 minute. PRODUCT MUST BE MIXED WITH A 4” DISPERSION BLADE AND A ½” VARIABLE SPEED 850 RPM DRILL. DO NOT ADD HARDENER TO RESIN UNTIL BATCH IS READY FOR MIXING. FAILURE TO ADD ALL POLY-CRETE SL AGGREGATE WILL RESULT IN IMPROPER CURE OF MATERIAL.

B. Pour the entire batch onto the floor and spread with a ½ V notched squeegee. Each kit of POLY-CRETE SL will yield 55 Sq. Ft. per kit. Check squeegee every 1,000 sq. ft. for wear. Have a new squeegee ready to avoid interruption in the process.

C. Use a flat trowel to cut in edges, drains and around equipment. For continuity of finish and to ensure that new batches of material are blended together without transition lines, use even pressure and trowel at a low angle using a sweeping motion. To remove squeegee lines and help the material level, immediately Loop Roll the material after it has been placed. The material should be rolled straight forward and back picking up the roller with each pass; this will avoid leaving divots in floor. After the squeegee lines have been removed the floor should be cross rolled side to side along the entire wet edge. The final cross roll should be completed within 12 minutes of mixing the product at 70°F.

D. While wearing spiked shoes broadcast the chips up into the air and let them fall into the floor. Make sure the broadcast is dispersed evenly over the entire floor area at a rate of 0.1lbs per square foot. Wait 15 minutes from start of mix before beginning the broadcast and complete broadcasting within 30 minutes from start of mix. Do not roll or walk back onto areas that have been broadcast. Allow POLY-CRETE SL to cure for a minimum of 8 hours at 70°F.

E. Use a stiff bristle broom to sweep off excess chip. Use a vacuum to remove chips around the edges and corners that are not accessible with a broom.

VENTILATIONPrior to any application, proper “negative pressure” ventilation must be established. Please refer to the CRYL-A-FLEX Ventilation Guidelines on our website.

SECOND BROADCASTA. Due to the short working time of Cryl-A-Flex products

mix only what can be placed in 10 minutes. Typical batch size is 1 gallon. The amount of CRYL-A-CURE activator powder used is based upon substrate temperature. Be sure to use an infrared thermometer to measure substrate temperature. Refer to the CRYL-A-CURE MIX CHART for appropriate amount based on ounces per gallon.

B. Measure out 1 gallon of CRYL-A-GLAZE G-201 resin. Then measure out appropriate amount of CRYL-A-CURE based on substrate temperature. First pour the CRYL-A-GLAZE G-201 into a 2-gallon mix pail, then add appropriate amount of CRYL-A-CURE.

C. Using a ½” 850 RPM drill with a Jiffler blade, mix the CRYL-A-GLAZE G-201 and CRYL-A-CURE for 30 seconds. *DO NOT ADD CRYL-A-CURE TO CRYL-A-GLAZE UNTIL BATCH IS READY FOR MIXING*

D. Pour entire batch in a 4” to 6” ribbon along the starting area. Use a 3” chip brush to cut in along edges, doorways, and drains.

E. Using a solvent resistant, 18” 3/8” nap roller, pull the material from side to side overlapping passes every 6”. Be careful not to leave any puddles. CRYL-A-GLAZE G-201 is applied at 80 Sq. Ft. per gallon over decorative chip.

F. Using a solvent resistant, 18” 3/8” nap roller, cross roll the material side to side overlapping the previous pass with half the roller width.

G. Broadcast chip up into the air and let it fall onto the floor. Make sure the broadcast is dispersed evenly over the entire floor area at a rate of 0.1lbs per square foot. DO NOT OVER BROADCAST. THIS WILL INHIBIT THE CURE OF CRYL-A-GLAZE G-201. Do not roll or walk back into areas that have been broadcast. CRYL-A-GLAZE will cure completely in 40 to 60 min.

H. Use a stiff bristle broom to sweep off excess chips. Use a vacuum to remove loose chips from around the edges and corners that are not accessible with a broom.

TOP COAT INSTRUCTIONSNOTE: Use Cryl-A-Top T301 for interior applications, and Cryl-A-Top T303 for exterior applications.

A. Due to the short working time of Cryl-A-Flex products mix only what can be placed in 10 minutes. Typical batch size is 1-gallon. The amount of CRYL-A-CURE activator powder used is based on substrate temperature. Be sure to use an infrared thermometer to measure substrate temperature. Refer to the CRYL-A-CURE MIX CHART for appropriate amount based on ounces per gallon.

DUR-A-FLEX, INC. has developed this document to help Facility Owners, Architects, Engineers, Specification Writers, and Contractors gain a better understanding of the importance of a properly prepared substrate, and the methods to achieve an appropriate bond. This document is intended to be a general guideline, for specific jobsite information, please contact your local DUR-A-FLEX Representative.

There are many satisfactory methods of preparing a substrate to receive a DUR-A-FLEX flooring system. The preparation method is typically chosen based on service requirements, time allowed for entire process and accessibility.

PERSONAL PROTECTION EQUIPMENT It is the responsibility of the surface preparation contractor and the flooring contractor to insure that all personnel are properly protected from hazards. DUR-A-FLEX is committed to promoting awareness regarding these potential hazards. All DUR-A-FLEX products are rated according to the Hazardous Material Identification System (HMIS). OSHA regulations specify when, where and how workers are to be protected. These regulations and the local OSHA officials should be consulted as necessary to insure proper protection, compliance with the law, and to avoid liability issues. Safety and health issues should be addressed prior to the start the job.

TESTING

MOISTURE CONCERNS

Please refer to the Floor Evaluation Guidelines in the Contractor’s Center of our website to assist in determining the condition of the concrete.

Testing For An Existing Sealer Test to see if the floor is “sealed” by pouring a small amount of muriatic acid on the floor in several spots. If it “froths” instantly, the floor is not sealed. If the acid doesn’t froth immediately, a sealer and/or paint is present and must be removed by scarifying, steel shot blasting or other mechanical methods.

Salt Contamination Testing Salt contaminated slabs that contain steel reinforcement are very susceptible to corrosion of the reinforcing steel. As the steel corrodes it expands causing cracking, delamination of concrete and any toppings bonded to it and eventually, structural failure of the slab. Obvious signs of chloride or salt contamination are spalled concrete with exposed, rusted reinforcing steel. Testing is recommended to determine the depth of contamination and the extent of corrosion activity. A Litmus Test for pH will determine the presence of chloride or acid contamination, if the pH is below 10.

Bond Test The purpose of the bond test is to make sure preparation method is adequate for the primer to bond to the substrate. The test is done only when applying MMA systems. For more information on bond test refer to CRYL-A-PRIME data sheet on our website @ www.dur-a-flex.com.

Surface Prep Guidelines (Continued)

REMOVAL AND REPAIR ASTM D 4258-83 Standard practice for surface cleaning concrete for coating. This practice includes surface cleaning of concrete to remove grease, dirt, and loose material prior to the application of coatings. Procedures include vacuum cleaning, air blast cleaning, water cleaning, detergent water cleaning, and steam cleaning.

Removal of bond inhibiting contaminants This includes, but is not limited to removal of oils, grease, wax, sealers, curing compounds, laitance, salts and any other hydrocarbon based materials. This will ensure that a good bond takes place between the resinous flooring and the concrete substrate.

Removal of Adhesives, Mastics and Membranes In many retrofit projects, existing tile, VCT or sheet goods are being replaced with polymer flooring systems. Removal of the floor finish will often leave a layer of some type of mastic, adhesive or membrane. In thin applications these materials can often be totally cleaned up by shotblasting the concrete. In thicker applications, the steel shot will tend to bounce, requiring additional preparation with the use of scarifying equipment or possibly even the use of chemical strippers. Wherever possible, consult the DUR-A-FLEX Tech Service Department or your local DUR-A-FLEX Flooring Contractor and schedule a site visit to investigate the best removal methods.

Removal of Existing Seamless Floor Like mastics and adhesives, the need to remove an existing seamless floor will occasionally arise. There has been much progress made in the development of equipment for removal of resurfacers. Typically, removal requires a heavy grinder with “rotating heads”. These heads can be outfitted with different “teeth” or carbide “blades” for removal of a particular type of overlay.

REASONS FOR SURFACE PREPARATION Surface preparation of a concrete substrate is required to remove surface laitance to create a surface profile and porosity for adhesion of polymer floor systems.

METHODS OF SURFACE PREPARATION Care should be taken to define the degree of abrasion required for the coating system so that the concrete will not be eroded beyond what is necessary. All concrete surfaces should be abraded to remove laitance and contaminants. The following Table describes the required profiles according to the ICRI guidelines for various coating systems.

Coating Coating Thickness

Concrete Surface

Profile (CSP) Sealers 3 mil CSP 2-3High-Build 10-40 mil CSP 3-4 Self Leveling 50 mils-1/8” CSP 4-5 Polymer Overlay

1/8-1/4” CSP 5-7

Shotblasting Shotblasting is the recommended method of surface preparation of concrete for most polymer floor installations. Shotblast equipment utilizes an alloy wheel spinning at high speeds to throw small steel particles at the substrate in a controlled, dry, 99% dust-free operation. This process removes surface contamination, adds profile and vacuums the concrete clean in one process. The size and angularity of shot, along with the travel speed of the unit, can be adjusted to determine the degree of the surface profile. Because shotblasting is a dry preparation process, it allows the installation to begin immediately after completion of prep (surface must be dry before blasting). Shotblasting will also identify weak areas in the surface of the concrete. NOTE: When selecting shotblast preparation for thin film coating systems (under 20 mils) be aware that a blast pattern or track lines may be visible.

- 3 -


Diamond Grinding Diamond grinding should only be used in areas inaccessible to shotblasting and then only with coarse diamond wheel.

Scarifying Scarifying is primarily used for the removal of deteriorated concrete, coatings and polymer flooring systems.

Hand Tool Hand tool preparation consists of the use of mechanical tools and equipment designed to abrade or chip away the surface of the concrete. Common tools available include chipping hammers, hand held diamond grinders and concrete crack chasing saws. These tools are typically used to make keyways, prepare edges against walls and columns.

TYPES OF SUBSTRATES Regular Concrete Regular concrete surface must be prepared with a steel shot-blast machine, scarifier or diamond grinder. Floors with oil, grime and grease should first be cleaned with Simoniz 969 Cleaner/Degreaser before preparing. Allow floor to dry. Good ventilation, fans and/or auxiliary heat will accelerate drying time. Do not use oil fired portable heaters.

Replacement of Structurally Deteriorated Concrete Replacement of structurally deteriorated concrete must be done in accordance with The International Concrete Repair Institute (ICRI) Bulletin. Patching material must be a DUR-A-FLEX approved patching material. Make sure of minimum cure time before installation of resinous flooring. DUR-A-FLEX flooring Contractors should be contracted whenever possible to complete these repairs appropriately.

Fiber Filled Concrete Fiber filled concrete must be burned with a propane weed burner, swept and vacuumed perfectly clean and then primed. When primer has completely cured, the floor must be sanded and tack ragged (This step may not be necessary for thick resurfacing systems).

Quarry/Ceramic Tile Quarry/Ceramic tile have been successfully resurfaced on many projects without removal of tile and setting bed. A site investigation along with cores through the entire slab will help identify the type of setting bed, the existence of any waterproofing membranes, additional toppings, or other unusual existing conditions. Water trapped within the floor will create long-term sanitation and performance problems.

If the tile is well bonded and placed over an unsaturated latex setting bed, the floor may be resurfaced as follows: Surface must be mechanically abraded with a steel shot-blast machine, scarifier or diamond grinder and vacuumed perfectly clean. “Tack rag” area to remove dust and to soften surface. Apply DUR-A-FLEX recommended Poly-Crete or Hybri-Flex systems or DUR-A-GLAZE TIECOAT II or CRYL-A-PRIME P-101 with CRYL-A-BOND MT primer to the entire area immediately and allowed to cure.

Existing Epoxy Coating/Resurfacer Existing seamless floors may be resealed or resurfaced from time to time due to excessive wear or the need to change the appearance or skid-resistance of the floor. The existing floor should first be cleaned and degreased with EZ-CLEAN floor cleaner/degreaser. It must then be mechanically abraded with a floor-sanding machine or a steel shot blast machine to totally remove gloss. Vacuum perfectly clean. “Tack rag” area to remove dust and to soften surface. Apply DUR-A-GLAZE TIE-COAT II to entire area immediately followed by subsequent epoxy coatings.

Plywood The plywood substrate must be sound and non-flexing under the expected load. Typical plywood substrate must be exterior or marine grade, new, clean, and smooth finish (NO KNOTS).

Two layers with staggered joints are required. Plywood should be positively fastened to the existing surface with a high quality construction adhesive as well as a 6” screw pattern.

For further information on plywood substrates, please contact your local sales representative or DUR-A-FLEX technical department.

Walls For Dur-A-Wall Applications:

Block wall: Apply Dulux (ICI) block filler to fill pores over new or existing concrete block following manufacturer’s instructions.

Drywall: Drywall must be finished to a level #4 or #5 finish prior to coating. Prime with ICI GRIPPER Multipurpose primer or GLIDDEN GRIPPER primer. Substrate will affect final appearance of wall coating.

Cast in place Concrete and Ceramic Tile: Use DUR-A-GLAZE RAPID PATCH for cracks, holes, spalls, and voids in concrete up to ¼” thick. Multiple applications of filler material maybe necessary. Sand or grind between coats to achieve a smooth surface.

NOTE: Tile and block grout lines may “mirror through” the finished system even though the surface is smooth.

CRACKS AND JOINTS Refer to Joint Guidelines for complete joint details on our website in the Contractor Center section @ www.dur-a-flex.com.

Use DUR-A-GLAZE RAPID PATCH for cracks, holes, spalls, and voids in concrete up to ¼” thick.

Flooring problems on concrete from vapor emission, dew point, alkalinity; pH, etc. cause millions of dollars in repair and

replacement costs annually. By recognizing potential problems, testing for and mitigating them, steps can be taken to ensure a long

lasting, successful flooring installation.

What is Moisture Vapor Emission?

Water is added to turn cement, sand and aggregate into a

concrete slab. There is a critical volume of water needed to

“hydrate” the concrete and an excess volume of water used to

make the concrete pour-able and workable. It is this excess that

can emit from the slab. Moisture is also a concern when the

concrete slab has no vapor retarder installed, or the vapor

retarder has been punctured.

How does moisture move through the slab?

Capillary moisture: ground water touches the bottom of the

concrete slab, and wicks into the concrete through microscopic

bleeder water channels until it reaches the coating surface. As

the water comes through the slab, it brings calcium/sodium salts

with it that can degrade the bond line and cause the coating to

delaminate.

Osmotic Moisture: actual water vapor transmission through the

concrete slab condenses again at the bond line and causes the

same problem as in the capillary moisture case. This can

happen when the water table is far below the slab with an

improperly installed or missing vapor barrier. Three conditions

are needed for osmosis to occur: a semi-permeable membrane,

which can be the polymer primer or the upper layers of the slab,

a gradient of ionic activity (soluble salts, which are indigenous

to concrete), and a source of moisture vapor. If any one of these

three things is removed, osmosis cannot occur.

Hydrostatic: the surrounding water table is higher than the

concrete slab on grade. Because water seeks its own level, it is

forced through the slab under pressure. Both the pressure and

the water cause the coating to delaminate.

The volume of moisture that can pass through a slab depends on

the porosity of the slab. Porosity is a direct result of the

water/cement ratio in the concrete mix design. As the

water/cement ratio increases, the porosity of the concrete

increases exponentially.

What is the traditional failure mode because of “moisture”

problems? There are two ways a polymeric floor can fail: (1)

the floor system was never able to bond properly at the time of

installation or (2) there were factors present at the time of

installation to cause the bond to fail. Symptoms of failure on an

already installed floor may include bubbles, blisters and/or

delamination.

What causes a polymeric floor to fail?

Traditional theory has focused primarily on moisture failure

such as capillary and hydrostatic, however more recent research

has found that although moisture plays a role, it may not be the

only factor. In reality, the presence of ionic compounds in the

concrete can also play a role. Specific ionic components of the

surface chemistry of the slab (the top 0 - 3/16”(5mm)), when

present at certain levels, can cause a failure to occur.

Concrete defects resulting from alkaline-silicate reaction (ASR)

or alkaline-aggregate reaction (AAR) within the slab may also

contribute to floor failure.

How do I test my floor?

the moisture limits for each type or Dur-A-Flex resin/flooring

system. If you are planning to use our Epoxy or MMA, Dur-A-

Flex recommends using in-situ Relative Humidity Testing per

ASTM F-2170 as a quantitative test method. Although

traditional calcium chloride testing may be used, RH differs in

that it is not significantly impacted by ambient temperature and

relative humidity conditions in the building and thus likely to

provide more accurate readings. The use of calcium chloride

testing on lightweight concrete on elevated decks is not

recommended.

In cases where a product can tolerate high levels of moisture

such as Poly-Crete, Hybri-Flex or Dur-A-Glaze MVP, Dur-A-

Flex may recommend that cores be taken and analyzed to

determine the levels of ionic components (salts) in the slab.

Dur-A-Flex offers in-house core testing using ion-

chromatography technology. Refer to the Dur-A-Flex Core

Analysis Program on our website for more information.

Note: Test results from cores taken after osmotic blistering has

already occurred may not be accurate due to the ionic

components transferring from the substrate to the blisters.

Rev. 0116

The following data is based on testing of a concrete substrate profiled per Dur-A-Flex Surface Preparation Guidelines and free of

any contaminants that could increase levels of the soluble ions listed. This data is to be used as a guide only. Please contact your

local Dur-A-Flex Sales Representative or the Dur-A-Flex Technical Departments for a thorough analysis of your results.

Normal Soluble Ion Levels in Pre-installation Acceptable Soluble Ion Levels

Substrate (parts per millions) in Substrate by Product (combined Na, K, Cl): Sodium (Na) ~200-800 ppm Epoxy, MVP, MMA , ACCELERA 1600 ppm

Potassium (K) ~200-800 ppm

Chloride (Cl) ~10-100 ppm Poly-Crete SLB, MD, HF (w/topcoats), 3200 ppm

Sulfate (SO4) ~1500-5500 ppm Hybri-Flex E, M or A

Poly-Crete MD, HF (no topcoats) 4800 ppm

In all cases, Dur-A-Flex, Inc. products must be applied as per Dur-A-Flex Application Instructions on structurally sound and clean

areas in which the concrete meets acceptable industry standards as defined in ACI Committee 201 Report, “Guide to Durable

Concrete.” Dur-A-Flex shall not be liable for bond failures caused by deficiencies in the substrate including, but not limited to, the

presence of ionic compounds or soluble salts, alkali silicate reaction, alkali aggregate reaction, shale-pop, and other expansive

reactions of aggregates and reinforcements. Dur-A-Flex recommends all concrete be tested for quality by a licensed petrographer.

Core analysis testing is recommended to rule out the potential for osmotic blistering caused by

higher than normal levels (see below) of soluble ion (salt) deposits at or near the surface. Refer to

the Dur-A-Flex Core Analysis Program.

New Concrete

(<1 yr. old)

Core testing is not required if NO concrete curing compounds, hardeners, or densifiers were used.

The use of any of these products may cause soluble ion (salts) deposits at or near the surface to

exceed normal levels (see below), potentially producing conditions for osmotic blistering. In these

cases Dur-A-Flex recommends a core analysis to determine if these levels are suitable for an

installation. Refer to the Dur-A-Flex Core Analysis Program.

WHY CLEAN YOUR FLOOR?Appearance: Your floor will look its best when it is clean. By establishing a scheduled cleaning program, the floor will continue to look and perform as it did when it was first installed.

Safety: No matter how aggressive the texture of your floor, if it is not cleaned properly, it can present a slip hazard. Emulsifying, rinsing and drying your floor properly will reduce the risk of a slip and fall incident.

Note: Wet environments need to be kept dry as possible to prevent slip and falls. Proper signage, non-slip shoes, floor fans, and walk-off mats will help prevent slip and falls in any facility

Service Life: The lifetime of your floor will depend upon how well you clean it. In aggressive use areas (i.e. kitchens and machine shops) contaminants such as oil, dirt, and grease work with water and bacteria to break down the floor.

FLOOR CLEANING PROCESS & TOOLSThe best way to clean a Dur-A-Flex floor is to use the recommended cleaning product and follow a six-step process. (Equipment needs vary between small and medium/large floor areas.)

Process Small Area Medium/Large Area

Sweep floor thoroughly Broom, Dust Mop Floor Sweeper, Broom

Apply cleaning product on floor surface Deck Brush, Foamer/SprayerAutomatic Floor Scrubber, Foamer/Sprayer

Automatic Floor Scrubber

• Wax strippers should never be used on a Dur-A-Flex Floor• Never use Enzyme based cleaners on a Dur-A-Flex Floor• DO NOT use “No-Rinse” cleaners as the chemical

concentration can increase in the residual film left behind• Combinations of chemicals can result in staining or

degradation if not properly rinsed and removed• Never use a mop to clean a floor that is greasy or oily. • Make sure the pads or brushes on the automatic scrubber are

in good shape. Pads should be non-abrasive white, tan or red 3M cleaning pads or equivalent. Brushes should be nylon non-abrasive Malish 8129 series or equivalent soft to medium flex nylon bristle brush.

• When using a deck brush, choose a medium/stiff bristle. • When using a floor cleaning machine, a pad is recommended for

use on smooth floor systems, while a soft to medium flex nylon bristle brush is recommended for broadcast floor systems or smooth floor systems with added texture.

• When removing solution with a squeegee, use a soft, neoprene squeegee. Do Not use a water spray to remove cleaning solution from the floor because it will over-dilute the solution and cause grease and oil to fall back onto the floor.

• Spills should be cleaned up immediately to prevent staining and as a safety precaution.

• Surfaces should be adequately protected when moving heavy equipment across the floor.

• Through proper training and education, unnecessary wear of the floor (such as forklift spin and skid-marks) can be avoided.

RECOMMENDED CLEANING PRODUCTSDetermining the correct cleaning product for your Dur-A-Flex floor is based upon the amount and type of soiling the floor receives. We have divided these into four types, and recommended a cleaning product for each instance:

The above Dur-A-Flex cleaning products may be ordered directly from Dur-A-Flex Customer Service at 1-800-253-3539 or via email at [email protected]

CONNECTICUT | GEORGIA | ILLINOIS | CALIFORNIAToll Free 800-253-3539 | 860-528-9838 | www.dur-a-flex.com

WHEN TO CLEAN YOUR FLOORDur-A-Flex floors are designed for and used in heavy traffic areas that typically accumulate foreign matter. Because of this, the recommended maintenance schedule for most areas is once or twice daily cleaning and regular “touch-ups” for spills. Less frequent cleaning of these areas results in a buildup of foreign matter, which diminishes the appearance, safety and service life of the floor.

Our CRYL-A-FLEX MMA products develop to full cure in one hour, and full cure for most epoxy and urethane systems is 7 days at 68°F. The lower the room temperature -the longer the cure time. Avoid chemical spills and full traffic during cure period. Premature exposure may cause permanent staining or discoloration. Do Not use abrasive cleaning methods during the first week after installation.

WALL CLEANING PROCESS1. Application – Apply EZ-CLEAN, follow cleaner guidelines for dilution rate, use with hot water while using a deck brush,

foamer/sprayer or power washer.2. Scrub walls with deck brush3. Rinse walls with clean water

Moving Joints

Construction, Expansion and Isolation joints are considered moving joints which allow horizontal and vertical movement between the slab and adjoining structures, such as walls and columns, helping to minimize cracking where the two meet.

Prior to filling moving joints Dur-A-Flex, Inc. recommends “honoring” these joints by making a saw cut through the finished floor system at a depth of ¾” deep and ¼” wide with a diamond blade saw attached to a vacuum. A bond breaker such as backer rod (closed cell) must be added to the bottom of the joint. Be sure to mark the location of the joints prior to the installation of the finished floor.

Potential cracking and or stress/stretch lines (white lines) may occur on all resinous floor systems over or on either side of moving joints if the joints are not saw cut and properly filled. Also if there is a variance of temperature of 20 degrees or more from the time the joint is filled and coated to its operational temperature, hairline cracking could occur even on non-moving joints.

Non-Moving Joints

Control and or Contraction joints are considered non-moving joints which accommodate shrinkage and relieve internal stresses during the curing process of the concrete.

The two basic joint types are Moving (dynamic) and Non-Moving (static).

20

Prior to filling non-moving joints be sure to prepare them by removing all laitance, debris and sealers to a depth of ¾”deep and ¼” wide with a diamond blade saw attached to a vacuum. A bond breaker such as silica sand (30-40 mesh) at ¼” deep may be added to the bottom. This will stop the joint material from seeping if the concrete is cracked through.

Repair of damaged/spalled joints

Saw cut each side of spalled area and chip out the center with a chipping hammer or consider the use of a series of blades to reach the proper width. If using multiple blades, the center blade should reach the depth of the original joint and the outer blades should achieve a cut creating a “T” shape after cutting.

Installation Timing

The American Concrete Institute (ACI) recommends that filling of industrial floor joints be deferred 60-90 days after floor slab pour or as long as possible. This is to allow control and construction joints time to open closer to their ultimate width through the concrete shrinkage process. (In freezer/cooler areas, floor should be stabilized at ultimate operating temperature for 7 days prior to installation).

Prior to treatment of joints be sure to contact the facilities owner or manager to determine how long the concrete has cured as well as the location of moving and non-moving joints.
